Computer light with extensible electric conductive wire

ABSTRACT

Computer light structure with extensible electric conductive wire, including a main body, a housing, an upper cover and a plug unit. A clip device and a lighting device are disposed on the main body. The housing encloses a lower side of the main body to define an interior space in which a winding device is accommodated. The clip device serves to clip an external article such as the panel of a portable computer for fixing the lighting device thereon to provide sufficient illumination. After used, the electric conductive wire can be quickly and smoothly wound back by the winding device to avoid tangle of the wire. In addition, the plug unit is clipped by the clip device to avoid random placement.

BACKGROUND OF THE INVENTION

[0001] The present invention is related to a computer light withextensible electric conductive wire, which is able to quickly andsmoothly wind back the wire to avoid tangle thereof.

[0002] Portable computers are widely used nowadays. However, in somecases, it is still inconvenient to use the portable computer. Forexample, in a dim place, a user cannot conveniently operate the computerand an auxiliary illuminating device will be needed.

[0003] A computer light has been developed for providing sufficientillumination for a user to operate the portable computer. Such computerlight includes an extension conductive wire one end of which is adaptedto be plugged into the portable computer, while the other end of whichis connected with a lighting device.

[0004] The above computer light has some shortcomings in use as follows:

[0005] 1. It is uneasy to store the computer light. When not used, theconductive wire of the lighting device is generally wound back and forthand tied with a rubber ring and soft string. Therefore, it istroublesome to store the computer light and the appearance thereof willbe poor. Moreover, after the conductive wire is unwound and stretchedfor next use, the conductive wire will be irregularly crimped. Thisleads to inconvenience in use.

[0006] 2. The conventional computer light is not durable. The extensionconductive wire is exposed to outer side. In addition, after repeatedlycurled and stretched, the wire tends to fail or break. This will lead topoor contact.

[0007] 3. The conductive wire of the conventional computer light is easyto tangle. The conductive wire has a considerable length. In the casethat after used, the conductive wire is not properly wound into alimited length, the conductive wire is easy to loosen and swing. As aresult, the conductive wire tends to tangle with external article. Thisleads to inconvenience in use.

SUMMARY OF THE INVENTION

[0008] It is therefore a primary object of the present invention toprovide an improved computer light structure with extensible electricconductive wire. The computer light includes a main body, a housing, anupper cover and a plug unit. The housing encloses defines an interiorspace in which a winding device is accommodated. After used, theelectric conductive wire can be quickly and smoothly wound back by thewinding device to avoid tangle of the wire. The winding device includesa resiliently rotatable winding reel for winding or unwinding the wire.A resilient member is disposed in the winding reel for constantlyproviding resiliently restoring force to drive the winding reel to windback the wire.

[0009] It is a further object of the present invention to provide theabove computer light in which when not used, the wire is smoothly woundinto the winding device and the plug unit is clipped between the clipdevice and the plug recess of the main body. Then the upper cover isoverlaid on the top face of the main body to cover and prevent the clipdevice, lighting device and the plug unit from being damaged orcontaminated.

[0010] It is still a further object of the present invention to providethe above computer light in which in use, the upper cover is reverselyfitted onto the housing to cover the housing without occupying otherroom and being randomly placed.

[0011] The present invention can be best understood through thefollowing description and accompanying drawings wherein:

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0017] Please refer to FIGS. 1 to 5. The computer light of the presentinvention includes a main body 1, a housing 2, an upper cover 3 and aplug unit 4. A clip device 11 is disposed on the main body 1. The clipdevice 11 is a cantilevered clip formed with a resilient bight section111 and a press end 112. A lighting device 12 is movably supported onthe bight section 111 by a universal joint 113. A plug recess 13 isformed on top face 18 of the main body 1 corresponding to the press end112. The main body 1 is further formed with an extension hole 14 throughwhich an electrical conductive wire 41 of the lighting device 4 passes.A locating board 16 is disposed under the main body 1 and a windingdevice 5 is mounted on the locating board 16. An engaging section 15 isformed on a lateral side of the main body 1. A peripheral rib 17 isformed along the periphery of the main body 1.

[0018] The housing 2 has an interior space 21 in which the locatingboard 16 and the winding device 5 are accommodated. The upper cover 3 isformed an engaging section 31 adapted to the engaging section 15 of themain body 1 for engaging therewith to cover the main body 1.

[0019] The winding device 5 includes a winding reel 51 which isresiliently rotatable and a resilient member 52 providing resilientlyrestoring force to drive the winding reel 51. A pivot shaft 531 isdisposed on a fixing board 53. The fixing board 53 has multipleextending plates 533 and fixing holes 532 for fixing the fixing board 53on the locating board 16. A sufficient length of electric conductivewire 41 is wound around the winding reel 51. An end of the wire 41 isconnected with the plug unit 4, while the other end of the wire 41 isconnected with the lighting device 12. A pivot hole 511 is formed at thecenter of the winding reel 51. One end of the resilient member 52 isconnected with the pivot shaft 531 of the fixing board 53, while theother end of the resilient member 52 is connected with the winding reel51. In a preferred embodiment, the pivot shaft 531 is passed through themetal fixing board 53 and electrically connected with the lightingdevice 12. The electric conductive wire 41 wound on the winding reel 51is electrically connected with the other end of the resilient member 52to form a circuit.

[0020] The pivot shaft 531 of the fixing board 53 is pivotally fitted inthe pivot hole 511 of the winding reel 51, whereby the winding reel 51can be smoothly rotated to wind or unwind the wire 41. The resilientmember 52 is connected between the pivot shaft 531 of the fixing board53 and the winding reel 51. The resilient member 52 constantly providesresilient force for winding the wire into the winding reel. Therefore,it is easy to wind and store the wire without tangle. Therefore, theusing life of the wire is prolonged. The lighting device 12 is disposedon the universal joint 113 of the clip device 11 so that theilluminating direction of the light device 12 can be adjusted. In notused state, the wire 41 is first wound into the winding device 5 and theplug unit 4 is clipped between the clip device 11 and the plug recess13. Then the upper cover 3 is overlaid on the top face of the main body1 with the engaging sections 31, 15 engaged with each other.Accordingly, the upper cover 3 can cover the clip device 11, lightingdevice 12 and the plug unit 4. In use, the upper cover 3 is reverselyfitted onto the housing 2 to cover the housing 2. The engaging sections31, 15 are also engaged with each other. Therefore, the upper cover 3will not be randomly placed.
